Word'ing it abit different so my meaning dosnt get lost in translation.
If you can controll every portion of a basketball game from tip off to game end then you can say that luck is not a factor but no team in history can or ever will do that.
You cannot pre-determain the actions and reactions of the oposing team, coaching staff, fans or refs at a game, its not possible and that middle ground of a action vs a reaction is where luck or bad luck comes in.
Then what defines something being "lucky" then? well something that falls outside the realm of the statistic norm is 90% of the time defined as eighter a fluke or being attributed to some degree of luck.
And what the Jazz have done, has fallen outside the realm of the statistic norm, thus i attribute some degree of luck to it as i attribute some degree of luck to Michael Jordans carrer.
